The ADC HiGain product family is the industry's first practical implementations of High bit-rate Digital
Subscriber Line 2 (HDSL2). HiGain products are fully compliant with the HDSL2 standard. Providing full-rate
T1 access using just a single copper pair, HDSL2 is a cost-effective solution and offers an open architecture. The
open architecture inherent in HDSL2 guarantees interoperability, allowing simple, economic accommodation of
network growth.
HiGain HDSL2 products provide 1.552 Mbps transmission on one unconditioned copper pair over the full Carrier
Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 American Wire Gauge (AWG) wire
or 9,000 feet of 26 AWG wire, including bridged taps.
